.1 I i -Washingtoi 1,havefinvented certain new and e 1 :f useful Improvements (1D. Automobile-Tires,

of which the-followingfis a specification.

, My.invention relates to resilient Wheels, adapted for use upon 'fautofnobiles or the like. I p

, An important object of the invention is I j to providea wheekof theabove mentloned 1 character whichpossesses the desiredfldegree of resiliency and is strongaud durable.

A further object of theinventionis to character having means for connecting the if: 4 elements of the rim or tire, upon the starting. of the vehicle, to avoid undue shocks or jarslf Other objects andadvantages of the ingvention willbe apparent during the course .of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like Y parts throughout the same,

Figure 1 is a side elevation of a wheel embodying my invention,

a Fig. 6 is a similar view showing the yielding1 connecting ring in theactive position, 'a 2 an enlarged scale, with parts broken away. In the drawings wherein for the purpose "of illustration is shown a preferred embodi- .ment of my invention, the numeral 10 designates the hub of the. wheel, carrying spokes 11, to the outer end of which is rigidly secured an innertire member 12, preferably formed of metal. This inner tire member is preferably approximately U-shaped in cross section and has annular sides or flanges 13,

as shown. The inner tire member 12 is provided. with an air inflating valve 14, of the i usual type carried by the ordinary pneumatio tire.

The numeral 15 designates a co-acting Specification of Letters Patent.

Fig. 7 is a view similar to Fig. 1, upon {Patented Au 19,1919.

"outer tire member, which is approximately U-shaped in cross section and has annular sides or flanges 16, disposed outwardly of and slidably contacting with the sides 13,

to form an airtight joint therewith. The.

outer tiremember 15 has its tread portion suitably curved in cross section and this member is preferablyformed of metal. A strip 17 v formed of leather, rubber or the like, is secured to the tread portion of the outer member 15. i

In order that the outer member 15 may 'be' assembled upon the inner member l2,

such outer member is constructed in a plurality of sectlons A, which have Joints B.

As shown in Fig. 3, one section A isequippedj with an outer tonguie 18, to engage an inner tongue 19 securedto the end of the adjacent section A, "said. tongues havin packing 20 arranged therebetween for affording an airtight joint, and being icone .nected by screws or rivets 21. Any other suitable form of joint may be employed.

Arranged upon the sides 13 and secured thereto by being soldered or brazed thereon are annular flanges 22, also receiving the inner ends of the sides 16. These flanges carry packing 23 slidably contacting with the sides 16 to form an oil-tight joint therewith. The flanges 22 aiford annular chambers 24:, adapted to receive oil through valve controlled inlets 25.

The sides 13 are provided upon their outer faces in contact with the sides 16, with annular grooves 26, in communication with ports 27, leading into the chambers 24 to receive oil therefrom and feed the same to the grooves 26. These grooves retain the contacting sides properly lubricated and effect a seal or air tight joint.

Arranged upon the edges of the sides 16 are suitably stiff and resilient rings 28, which are secured to these edges by staples 29 or the like, which permit of the slight turning or rolling movement of the rings upon the edges. The rings 28 are positioned within the flanges 22, and are adapted to contact with the inner inclined ends 30 thereof.

Bolts 31 or the like are secured to the sides 13 and pass through the rings 28, as shown.

The operation of the wheel is as follows:

Compressed air is supplied into the tire through the valve 14 from a pump or the like, in the usual manner. When the tire is inflated the outer tire member 15 is adapted g h g V to yield slightly with relationtothe inner tire member, so that the tire functions as the, 1 ordinary pneumatic: tire. r the" vehicle, the inner tire member: 12. is
